What is the oxidation number of cu2so4?
+2
The oxidation state is therefore +2. Recognize the formula as being copper(II) sulfate (the (II) designation indicates that copper is in a +2 oxidation state, as discussed below).
What is the oxidation state of 2H2O?
Answer. Oxidation numbers are assigned to individual atoms within a molecule. So, the fact that there are 2H2O in an equation doesn’t affect the oxidation numbers of the individual atoms. So, in H2O, whether you have one molecule or a bathtub full, H has an oxidation number of +1 and O has an oxidation number of -2.
What is the oxidation state of Cu+ AQ?
In its compounds, the most common oxidation number of Cu is +2. Less common is +1. Copper can also have oxidation numbers of +3 and +4.
What is the molar mass of Cu2SO4?
223.1546 g/molCopper(I) sulfate / Molar mass
What is the oxidation number of 2H2O2?
-1
What are the oxidation numbers in the compound H2O2? The oxidation number of O in compounds is usually -2, but it is -1 in peroxides. The oxidation number of H is +1 For two H atoms, the sum is +2.
In which compound is the oxidation state of hydrogen not 1+?
metal hydrides
In this, the hydrogen is present as a hydride ion, H-. The oxidation state of a simple ion like hydride is equal to the charge on the ion – in this case, -1….Working out oxidation states.
element | usual oxidation state | exceptions |
---|---|---|
Hydrogen | usually +1 | except in metal hydrides where it is -1 (see below) |
Fluorine | always -1 |
Is the oxidation number of Cu always 2?
Elemental copper, Cu(s), has an oxidation state of zero (0). For copper(II) nitrate, Cu(NO3)2 : Copper is +2, since two nitrates are each -1. Next identify the compounds that have changed oxidation states.
What is the ionic compound of cu2so4?

What is the oxidizing agent in 2H2 O2 → 2H2O?
O2
In this reaction, Oxygen is making Hydrogen to lose electrons, so O2 is oxidizing agent. Hydrogen is losing electrons so H2 is reducing agent.
What is the oxidation number of oxygen and sulphur in copper?
In this case, the oxygen atoms have -2 oxidation number, and sulphur +6, so (4 x -2) + 6 = -2 so the copper must be +2.
What is the correct name for the ionic compound CuSO4?
The proper name for CuSO4 is copper(II) sulphate – the Roman numerals denote the oxidation state for any atom which has variable oxidation states, such as transition metals. There are several ways to work this out. We could start from a knowledge that the sulphate ion has a 2- charge,…
What is the oxidation number of hydrogen hydrogen?
Hydrogen has an oxidation number of +1 when combined with non-metals, but it has an oxidation number of -1 when combined with metals. The algebraic sum of the oxidation numbers of elements in a compound is zero. The algebraic sum of the oxidation states in an ion is equal to the charge on the ion.
How do you determine the oxidation state of a carbon atom?
The oxidation state of any chemically bonded carbon may be assigned by adding -1 for each bond to more electropositive atom (H, Na, Ca, B) and +1 for each bond to more electronegative atom (O, Cl, N, P), and 0 for each carbon atom bonded directly to the carbon of interest. For example:
